ZF 4699.170.061 MOTOR | OEM Genuine Part

Overview

The ZF 4699.170.061 MOTOR is an OEM genuine hydraulic motor designed to convert fluid power into mechanical rotation within ZF powershift transmissions. This component is integral to the transmission’s hydraulic control system, providing the necessary torque to actuate clutch packs and shift gears under load. As a critical element in construction machinery drivelines, the 4699.170.061 motor ensures precise modulation of hydraulic pressure for smooth engagement and disengagement of drive elements. The SKU 4699.170.061 is engineered to meet ZF’s exacting tolerances, guaranteeing direct fitment and long service life in demanding environments such as wheel loaders and graders.

Symptoms of Failure

When the ZF 4699.170.061 MOTOR begins to wear, operators may notice several distinct performance issues. One common symptom is erratic gear engagement or delayed shifting, where the transmission hesitates before moving into gear due to insufficient hydraulic pressure from the motor. Another sign is intermittent loss of drive under load, often accompanied by a whining noise from the transmission housing. Operators may also experience oil contamination or metallic debris in the hydraulic fluid, indicating internal wear of the motor’s rotating group. Finally, overheating of the transmission oil can occur as the motor struggles to maintain flow, leading to reduced efficiency and potential damage to surrounding components like the HOUSING.

Technical Specifications

Compatibility

This motor is primarily used in ZF’s WG180 and WG200 series powershift transmissions, which are common in mid-sized construction machinery. It also fits select variants of the WG150 and WG250 models, particularly those equipped with hydraulic clutch modulation. The 4699.170.061 motor interfaces directly with the BASIC PARTS kit and the WHEEL SHAFT assembly. For full compatibility, verify your transmission’s serial number against ZF’s application guide, as the motor’s mounting flange pattern may vary between early and late production units. The PLANET CARRIER in these transmissions also relies on the motor’s consistent hydraulic output for proper torque distribution.
